Reddened skin on the face is typically caused by an allergic rash or skin irritation, and rosacea is commonly attributed to this problem, according to Everyday Health. The skin discoloration starts as an increased facial flushing that transitions to a permanent facial reddening. In some cases, rosacea has thickened, bumpy skin and prominent blood vessels, according to Healthline.

Vitiligo causes skin discoloration, and it results in the gradual lightening of different areas on skin, according to Healthline. This skin problem can affect a small area or develop large patches. Dermatologists believe that this type of skin discoloration is caused by issues with the immune system, according to Healthline.

Darker skin, or hyperpigmentation, is caused by venous stasis, which is caused by a limited blood flow in the veins. The effect on the skin is known as stasis dermatitis, according to Healthline. Patients experience a gradual darkening or thickening of the skin, and the ankle area commonly displays the discoloration.
